July 10, 2014 – A fan speed control sensor for Rittal’s TopTherm fan-and-filter units automatically adjusts the fan speed in response to changes in temperature inside the enclosure. The device solves the problem of fan-and-filter units running continuously, even when not required, helping to reduce energy consumption and, consequently, running costs, the company says. With a fixed set point of 35 degrees C, the device provides continuous control with fan speeds varying linearly between 10 per cent at 20 degrees C and 100 per cent at 35 degrees C. No additional power supply is required because the sensor takes a 10 VDC feed from the fan-and-filter unit.
